Unless my math is wrong your burning 350ish L of fuel a month? I thought the interior was for hippies?
I just had a quick look through my records for the last year, seems my estimate was a bit high since I appear to burn closer to 75 L a week, or 300 L a month +/-
In the summer I commute a fair bit for work, a little bit of shuttling, camping on the weekend every so often, visiting friends who live in the country etc.
In the winter I dont drive as much because I'm not working, but I suppose mileage drops because I'm pretty much locked in 4x4 for half the year.
These figures are for a small domestic SUV, get's the same mileage as a brand new Toyota Tacoma that just rolled off the lot.
As someone else pointed out earlier, in the sticks people are still learning what public transportation is..we barely have any bus service let alone decent bike lanes etc and most rural communities are very spread out.
